It is good to get in touch with your inner child from time to time，and obviously some people are willing to pay big money for the chance to do so in a proper environment．A Brooklyn-based adult preschool is charging customers between $333 and $999 for the chance to act like a kid again．

At Preschool Mastermind in New York adults get to participate in show—and—tell，arts—and—crafts such as finger paint，games like musical chairs and even take naps．The month-long course also has class picture day where the adults are expected to have a field trip and a parent day.30-year-old Michelle Joni Lapidos，the brain behind the adult preschool，studied childhood education and has always wanted to be a preschool teacher．She's always on the lookout for new ways to get people in touch with the freedom of childhood．A friend encouraged her to start the mastermind course instead．

    According to Candice，her blogger friend，Preschool Mastermind gives adults a chance to relearn and master the things that they failed to understand as children．“I realized all the significances of what we learn in preschool，”said founder Michelle Joni，“People come here and get in touch with their inner child．It's magical．We are bringing ourselves back to another place，another time with ourselves when we are more believing in ourselves，more confident and ready to take on the world.”

    “One person's here because they want to learn not to be so serious．”Michelle said．“Another's here to learn to be more confident.” She explained that most of the classes were planned．However，Joni added that while the planned activities were fun，it was often the spontaneous(自发的)moments that attracted students．“It's the things you don't plan for，the sharing between friends and learning from each other.''

    When Wu Jia, then aged 23, returned from Canada to work for her father's Hangzhou-based Zoland Animation (动画) in 2007, she found Chinese animation productions were just-so-so. Back then, Chinese animation shown at overseas events, received a poor response.

    But things soon changed following a boom in China's movie and television industries. By 2011, China developed into one of the world's largest animation producers, with animation and cartoon products reaching a record of 260,000 minutes.

    However, that figure has witnessed a fall in recent years. The latest statistics show that China made only 244 animated productions totaling 83,600 minutes in 2017. But Wu says: “Chinese animators are changing from quantity to quality and Chinese animators are now producing more quality works” at the 14th China International Cartoon & Animation Festival.

    Wu, now the chairman of Zoland Animation, is among those who are part of China's rapidly growing animation industry. She says the company has so far displayed more than 8,000 hours of animated content to 93 countries and regions, including the United States, United Kingdom, France, South Korea and Russia.

    Magic Eye, one of Zoland's most popular animated works, which was sold to just Singapore in 2006, is now reaching the screens of nearly 80 countries and regions worldwide. The 500-episode animated series about an alien boy's adventures on Earth also has a sequel (续集) series Magic Eye is Back, which has 104 episodes. Thanks to Magic Eye's popularity, the sequel quickly arouses interest in overseas markets and is being displayed in 38 countries and regions.

    Speaking about how to succeed abroad, Wu says: “First, the works should be good. And, you need an experienced team who knows international markets.”

    A new study shows that rising levels of planet-warming gases may reduce important nutrients in food crops.

    Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.

    In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions. However, vitamin E levels increased by about 13 percent on average.

    The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyo's Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.

    One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern is there are many more surprises to come,” he said.

    Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depend on over millions of years without having effects come back to affect our own health.

    The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.

    Nearly everyone has bad habits. That's because, try as we might, bad habits are hard to break. On the other side, good habits, such as eating more healthfully or exercising regularly, never seem to stick. As a result, most people throw up their hands and surrender.

    But now a new book, Better Than Before: Mastering the Habits of Our Everyday Lives by best-selling author Gretchen Rubin, offers some useful solutions.

    Rubin, who became interested in habits during her research on happiness, which resulted in two popular books, The Happiness Project (2009) and Happier at Home (2012), found that our inability to master unwanted behaviors was a major downer (令人沮丧的因素). So, after guiding millions of readers down the path of true contentedness, Rubin turned her investigative skills toward habits.

    Her most important find? Change is possible if we do some soul searching and identify how we respond to expectations. And, just about everybody falls into one of four personality categories: Questioners, Obligers, Rebels and Upholders.

    Rubin believes herself to be a classic Upholder, someone who forms habits relatively easily because she responds well to both other people's deadlines and her own. As to the other types, Questioners will only form a habit if it makes sense to them; Obligers work hard to meet other people's expectations but often let themselves down. And Rebels resent (反感) habits.

    "Think about the habit that you want to form and then think: "What's everything I could do to set myself up for success?" says Rubin. For example, if you want to exercise more and you're an Obliger, call your friend who lives across the street and meet at 6：30 every morning for a walk.

    One common pitfall (陷阱), says Rubin, especially when it comes to changing your diet, is lack of clarity (清楚). "You can't make a habit out of eating more healthfully, "she says. Instead, your habit should be something like: "I'm going to pack a lunch every day and bring it to work instead of eating out."

    As for exercise, Rubin recommends a strategy called pairing—coupling two activities, one that you need or want to do and one that you don't particularly want to do. Rubin, for example, only allows herself to read magazines while on fitness equipment at the gym.

"Having the world at our fingertips" is a metaphor often used when we put our hands on information technology, like smartphones and computers. This is a good metaphor. But what is much better is how we use our hands to make things done.

Put one hand flat on a surface, palm down, and you might be able to make out the outline of 14 short bones in your thumb and fingers, in addition to 5 longer ones in your palm that are jointed to your wrist. These bones give each hand its rigid, knuckled structure. Together they're critical components of the anatomical （解剖的） architecture that allows your hand to move. At each of your fingertips there's an ever-growing, translucent plate of fibrous protein, otherwise known as a nail. Although they're nice for decoration, your nails protect and enhance your sensitivity to touch, too.

Imagine squeezing a piece of paper between your thumb and index finger, for example. We use this type of forceful pad-to-pad precision grasping without thinking about it, and literally in no time. Yet it was a breakthrough in human evolution. Other primates （灵长目动物） exhibit some kinds of precision grasps in the handling and use of objects, but not with the kind of efficiency that our hand does.

With a unique combination of traits, the human hand shaped history. No question, stone tools couldn't have become a keystone of human technology without hands that could do the job, along with a nervous （神经的） system that could regulate and coordinate the necessary signals. Even for those who have never attempted to make a spear tip or arrowhead from a rock, it's obvious that it would require strong grasps, constant rotation and repositioning, careful strikes with another hard object. And even for those who have done so, it can be a bloody business.

Of course, the most common object that people touch nowadays is a screen. And the tap-tap-tap movement of our fingers is a unique human ability, as no other primate can move their fingers as rapidly and independently as we do. Here again, we can thank the extraordinary human brain given that normal finger tapping requires the functional integrity of different parts of our central nervous system.
